Here is the statement United Airlines posted on its website Thursday following a news conference by lawyers for Dr. David Dao, who was forcibly removed from a flight after refusing to give up his seat:

We continue to express our sincerest apology to Dr. Dao. We cannot stress enough that we remain steadfast in our commitment to make this right.

This horrible situation has provided a harsh learning experience from which we will take immediate, concrete action. We have committed to our customers and our employees that we are going to fix what's broken so this never happens again.

First, we are committing that United will not ask law enforcement officers to remove passengers from our flights unless it is a matter of safety and security. Second, we've started a thorough review of policies that govern crew movement, incentivizing volunteers in these situations, how we handle oversold situations and an examination of how we partner with airport authorities and local law enforcement. Third, we will fully review and improve our training programs to ensure our employees are prepared and empowered to put our customers first. Our values - not just systems - will guide everything we do. We'll communicate the results of our review and the actions we will take by April 30.

United CEO Oscar Munoz and the company called Dr. Dao on numerous occasions to express our heartfelt and deepest apologies.
